As indicated by Phillips and Emery (Proc. U. S. Nat. Mus., vol. 55, 1919, 

 p. 435) Isosoma Walker is preoccupied in Coleoptera by Isosoma Billberg, 

 making it necessary to substitute the generic name Harmolita Motschulsky 

 for that of Isosoma. Phillips and Emery restricted Harmolita to those species 

 of Isosoma having no umbilicate punctures and a non-carinate occiput. The 

 effect of this was to leave many species formerly placed in hosoma without a 

 generic name. Inasmuch as it is impossible to determine from the description 

 of many species whether they would fall within or without this restricted defin- 

 ition, the writer has considered it better, for the purposes of this paper, to treat 

 Harmolita as the full equivalent of Isosoma Walker et Auct.
